Abstract(J)Fialaモデルを用いタイヤの設計パラメータ(トレッド, ベルト, サイドウォールの各剛性および接地長)と旋回剛性との関係式を導く. 本式にエア圧と荷重に対する各設計パラメータとの回帰分析より得た回帰係数を与えることで, 短時間で, 旋回剛性の予測を可能とする. 本手法は, タイヤ設計開発期間の短縮化に効果的である.

Translation

Abstract(E)In the present study, estimation method of cornering stiffness is presented against the changes of tire stiffness and its air pressure, using Fiala model together with regression analysis. For this purpose, empirical formulations of lateral spring constant, foot print, and belt stiffness, which are needed to estimate cornering stiffness, are investigated. This study makes the estimation of cornering stiffness possible , when tire design have been changed , and the author believes it is a effective tool to shorten the tire development periods.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
